Accelerator wire should be adjusted when removing and replacing any parts of the Accelerator Control Sys-
tem, shown in the illustration.
REMOVAL
1.    Remove engine cover. Refer to EM-11, "ENGINE ROOM
      COVER" .
2.    Loosen lock nut, and remove accelerator wire from throttle
      drum.
3.    Remove accelerator wire from accelerator pedal.
4.    Remove accelerator wire bracket bolt and nut, and pull acceler-
      ator wire into vehicle interior.
5.    Remove accelerator pedal bracket nuts, then remove accelera-
      tor pedal and bracket assembly.
                                                                                                     SBIA0330E


INSTALLATION
Install in reverse order of removal procedures, paying extra attention to the items below.
CAUTION:
q    Do not leave scratches, twist or bends on accelerator wire cores.
q    Do not apply lubricant to inside accelerator wire.
q    Check if accelerator pedal is free from contact with other parts, and releases smoothly.
q    For ASCD wire adjustment, refer to ACS-29, "ASCD Wire Adjustment" .

Adjusting Accelerator Wire
1.   Loosen lock nut and adjusting nut.                                                                        A
2.   Tighten accelerator adjusting nut until throttle drum starts to move.
3.   From that position, turn back adjusting nut 1.5 to 2 turns.
                                                                                                               ACC
4.   Tighten lock nut to specified torque holding adjusting nut.
INSPECTION AFTER INSTALLATION
q    Check if throttle drum opens fully when accelerator pedal is fully depressed to the floor, and operates   C
     smoothly in all process.
q    Check if throttle drum returns to idle position when pedal is released.
q    Check if the ASCD wire is not pulling the throttle drum.                                                  D
